koolstoffaand
Koolstoffaand, often referred to in English as carbon fiber tow or carbon strand, is a high-strength, lightweight filament made predominantly of carbon. It is produced from a polymer precursor such as polyacrylonitrile (PAN) or a pitch-based precursor, which is spun into fine filaments and then subjected to stabilization, carbonization in inert atmosphere at high temperatures, and, in some cases, graphitization to increase stiffness. The resulting carbon fibers are bundled into tow or formed into yarns for weaving into fabrics or consolidated into prepregs with resin matrices.
Properties: Carbon fibers have a high tensile strength-to-weight ratio and high stiffness, along with good corrosion
Manufacturing specifics: A tow is a bundle of filaments; the designation 'k' (as in 3k, 12k, 24k)
Applications: Carbon fiber strands are used to reinforce composite materials in aerospace, automotive, sporting goods, wind
Environmental and safety notes: Production involves high temperatures and chemical processing; end-of-life disposal and recycling remain
